HEATER. FOR FREIGHT-cans.

memorie.

To all whom t may concern:

Be it known that I, GEORGE G. BYNE, citii zen of the United States, residing at Tulsa, 'in the county of Tulsa and State of Oklahoma, have invented a certain new and usevful Improvement in Heaters for Freight- Cars, of which the following is a specification.

My invention relates to improvements in portable heaters, and the object f my invention is to provide a portable heating apparatus which shall embody a stove for burning fiuid fuel, a tank for fluid fuel under low pressure, a desired number of containers adapted to hold a'supply of fluid fuel under high pressure, reducing valves, and a thermostatically controlled valve, all of which sired. -I attain this object by devices illuswhereiny Figuree1-is a view in side velevation of some of the principal parts of my invention K as disposed within a portable inclosure which is shown in vertical section on broken line of Fig. 2, and Fig. 2is a plan view of the chief parts of my invention as disposed` in said portable inclosure which is shown in horizontal section on broken line 1, y of .'Fig. 1.

Referring to the drawin s, throughout which like reference numera s indicate like parts, the numeral' indicates a lstove of any form of construction thatmay adapt it to burn fluid fuel, as volatile Oils or gases and such stove 5 is connected with a tank 6 that is constructed to adapt it to serve as a chamber for containing Huid fuel under a comparatively low pressure and such tank 6 is -connected through a thermostatically controlled valve 7 and a conducting pipe- 8 with the burner tip 9 of said stove 5, which burner tip 9 is indicated by dotted lines in Figs. 1

and 2 and said tank' 6 is also provided with another outlet passageway which serves as a by-passaround the valve 7, and which consists of apipe 10 which leads to and connects with a T 11, fiom which T 11 extends a valrv'e controlled pipe 12, thatconnects with the pipe 8, and a. valve controlled pipe 13 which leads to the point of combustion adj acent to the burner tip 9 (as indicated by said dotted lines in'Figs. 1 and 2), whereby fluid fuel may if desired, be permitted to flow from the tank 6 to the burner tip 9 without passing through the valve 7 and whereby fluid fuel may, if desired, flow directly from the tank 6 through the pipes 10 and 13 to the pointof combustion to issue from the end of said pipe '13 in the form of a small jet that may be ignited to serve as a pilo't lighter that may be caused to burn constantly thus immediately to ignite any fuel that may issue .from the burner tio 9.

The valve-stem of the valve 7 is connected with a connecting rod 14 which extends Iupwardly and its upper end is articulated with one end of ay lever 15 which is pivotally mounted to oscillate on a bracket 16 that is disposed on the top of the "tank 6 and the other end of said lever 15 is associated with Ithe mechanism of a thermostat 17, which mechanism may serve to oscillate said lever 15 to actuate the valve 7 -to control the flow of fuel therethrough in responsev to variations inthe temperature of the atmosphere to which the thermostat 17 is subjected.

I have not illustrated the plan construction of the thermostat 17 since. one of the different well knownl forms of thermostats may be employed and since I make no claim of any particular form of thermostat.

A plurality of cylindrically formed containers 18, 19, 20, 21 and 22 are connected to-v gether, in series, by conducting pipes 23, 24,

aul

25 and'26, respectively, as indicated in Fig.

2, and the container 18 forming one` end of said series is connected by a conducting pipe 27 With an elbow 28 that communicates with the interior of the tank 6 through the top wall thereof and interposed in each of said conducting pipes 23, 24, 25, 26 and 27 is a reducing valve 29 of a well known form of construction.

Since the tank 6 is intended to contain fluid fuel under a low pressure only such tank 6 may be made of thin sheet metal that is strong enough to resist such low pressure but in order to obviate injury to such tank l6 due to its accidental subjection to an abpressure of twelve hundred pounds to the square inch, under which pressure each of such containers may have forced into ita quantity of fluid fuel which under a normal pressure would be in a gaseous form, but which under such pressure of twelve-hundred pounds per square inch would be in liquid form and which quantity under such high pressure would contain a great number of thermal units. Each of said containers 18, 19, 20, 21 and 22 is provided with a hand operated valve, as valves 31, which valves 31 serve to control the passageway from its respective container into the respective ones of the conducting pipes 23, 24, 25, 26 and 27 and the pipe connections between adjacent ones of said containers 18, 19, 20, 21 and 22 and between the container 18 and the tank 6 are adapted to be connected and disconnected whereby any of them may be removed and replaced as may be desired, and such pipe connections include nipples extending oney from each of opposite sides of each of the valves 31, like nipples 35 and 36, 'as shown more clearly on the container 22 in Fig. 2, and when a container is disposed at the end of the Series of containers which is most distant from the tank 6, as, for instance, like the container 22 of Fig. v2, then one of said nipples, is, for instance, the nipple 35 has its open end closed by a cap 37.

All of the containers 18, 19, 20, 21 and 22 together with the tank V6 and the stove 5 are disposed within a portable inclosure 32 which is mounted on casters 33, which inclosure is provided with a door 34. and which is preferably made of woven wire, as Shown, thus to permit a free escape of heated air to the surrounding atmosphere.

I have provided the stove 5 with va flue which may be extended to a point outside ofthe car or room to be heated, through which products of combustlon may escape from v said stove 5.

fuel, as, for instance, an infiammable gas is forced Within the container until the p-ressure therein is of a desired high degree or until such gas becomes liquefied whereupon the Valve 31 is closed and when all 'the containers are so charged they may be replaced Within the inclosure 32 and connected in assoclation with the reducing valves and gas tank 6, as Shown in Fig. 2, and then the inclosure 32 is rolled to a desired position pounds then the reducing valve 20 between the container 18 and the tank 6 .will operate to permit the flow of fluid fuel from the container 18 into the tank 6 only when the pressure within said tank 6 is at a desired pressure, as for instance, four pounds or at a pressure less than four pounds, and, therefore, when the tank 6 is charged atI a pressure of four pounds the reducing valve 29 will' interrupt the flow of fluid fuel into said tank 6.

The tank 6 being charged at the pressure of four pounds the valve in the pipe 13 is opened-and the jet of fiuid fuel which will then issue from its end adjacent to the burner tip 9`may be ignited to serve as a pilot lighter and if the temperature to which the thermostat 17 is` subjected be lower than required'such thermostat 17 (being adjusted to operate at a desired predetermined degree of temperature) then such thermostat 17 will actuate the lever 15 to cause the connecting rod 14 to open the valve to admit fluid fuel into the pipe 8 from the tank 6 to supply the burner tip 9 whereupon such fluid fuel issuing from the burner tip 9 will be ignited by the pilot lighter, and the stove 5 will then heat the surroundingatmosphere to the required temperature, but if the surrounding atmosphere becomes warmer than the desired predetermined degree for which the thermostat 17 is, then, in Such case, said. thermostat 17 ,will actuate the lever 15 to decrease the flow of fiuid fuel through the' Valve 7 to the burner tip 9, or Wholly interrupt such flow as required; thus any variation in the temperature of the surrounding' atmosphere will var, of fluid fuel 'through the valve 7.

As the fluid fuel flows from the tank 6 to be consumed by the stove 5 the pressure in said tank 6 will tend to decrease below four pounds but the reducing valve 29 upon the y or 'interrupt the flow eginning of such decreasewill be actuated to g admit more fluid fuel from the container 18 thus to maintain the pressure of four pounds per square inch inthe tank 6 and when the quantity of fluid fuel within Athe container 18 is reduced to such point that the pressure therein is four pounds or less then the re-` -ducing valve 29 interposed in the pipe 23 will be actuated to admit fluid fuel from the container 19 into the container 18; and when the pressure in the container 19 is reduced to four pounds or less4 then the reducing valve 29 interposed in the pipe 24 will operate to permit fluid fuel to iow from thecontainer 20 into thecontainer 19 and in a like manner the fluid fuel contained in containers 21 and 22 will be permitted successively to flow toward the tank 6.

The pressure in the container 19 will not be changed from its. initial pressure of twelve changed until the pressure in the container 20 is four pounds per-square inch or less and the initial pressure in .the container 22 will not be changed. until the pressure in the container 21 is reduced to four' pounds per square inch or less and when the initial pressure in the container 22 is reduced to four lpounds per square inch or less then all the containers may be ldisconnected and recharged Aand then again connected inthe manner shown in Fig. 2 to be ready for further operation.

` :fluid fuel around the valve 7 maybe operperature than that ated by hand, if it be desired to heat the surrounding atmosphere to a higher temdegree for which the thermostat-17 is adjusted. l

, Of course any number of containers may Abe connected 1n series or only one container as the container 18 may be employed-when the stove is to be operated for a correspondingly shorter period of; time, and the form of the portable inclosure32 may be modied to suit different conditions of use, and, if desired, pressurev gages may be connected with the tank 6 or with the pipes extending.

between adjacent ones of the containers 18,

19, 20, 21 andr 22 whereby. to indicate the pressure within said tank and said container.

VManifestly, changes may be made in the forms and dimensions of the different parts of my invention without departing from the spirit thereof.

What I claim is:

1. In a heater of the class described, the combination with a stove adapted to burn fluid fuel, of a tank adapted to contain iuid fuel under al desired low operating pressure, a thermostatically controlled passageway for fluid fuel leading from said tank to the burner of said stove; a burner tip for a pilot light disposed adjacent to said burner of said stove; a valve controlled pas sageway leading from said tank to said burner tip of said pilot light; a valve controlled bypathforming an independent passageway between said tank and said burner .of said stove; a safety valve associated with said tank and adapted to operate when the pressure within said tank isincreased to a predetermined degree; a container adapted to contain iuid fuel under a high pressure; a pipe for conducting fluid fuel from said container to said tank; and a reducing valve interposed in said pipe whereby the pressure in said tank may not be increased above a desired predetermined degree .by the flow of iiuid fuel from said container into said tank.
